Dances with fire
i know bare bottom or sand bottom but why bb?????????? i'am some what new to reefing and i don't understand.
to add alittle bit to l.d.'s statement with the added flow we are looking to keep the detritus from settling at all (though there may be some small pockets ) keep it in the water column and down to your sump where the skimmer can do its thing .between the siphoning and skimmer you are able to 'export' the detritus , which inturn allows you to maybe feed your fish a little more .leveldrummer said:you can turn up the flow and blast the bottom of the tank so no poop settles on it, or when you vaccum, you get it spotless. its much easier to clean and keep clean.
